Abstract: front page image
(EN) A method for multi-user transmission in a wireless LAN system according to one embodiment of the present specification comprises the steps of: individually performing, by a STA including a first directional antenna and a second directional antenna, a first countdown procedure for the first directional antenna and a second countdown procedure for the second directional antenna according to a directional CCA operation for the first and second directional antennas; determining the first directional antenna as a primary antenna when the first countdown procedure is completed before the second countdown procedure; determining whether the second directional antenna is idle from a threshold time before a completion time point of the first countdown procedure to the completion time point; and transmitting multiple streams on the basis of the first and second directional antennas according to the result of the determination.
(FR) Un mode de réalisation de la présente invention concerne un procédé de transmission multi-utilisateur dans un système de réseau local sans fil comprenant les étapes suivantes : réalisation individuelle, par une STA comprenant une première antenne directive et une deuxième antenne directive, d'une première procédure de compte à rebours pour la première antenne directive et d'une deuxième procédure de compte à rebours pour la deuxième antenne directive conformément à un fonctionnement CCA directif pour les première et deuxième antennes directives; détermination de la première antenne directive en tant qu'antenne primaire lorsque la première procédure de compte à rebours est terminée avant la deuxième procédure de compte à rebours; détermination si la deuxième antenne directive est en état de veille à partir d'un seuil de temps avant un instant d'achèvement de la première procédure de compte à rebours jusqu'à l'instant d'achèvement ou non; et transmission de multiples flux sur la base des première et deuxième antennes directives conformément au résultat de la détermination.
(KO) 본 명세서의 일 실시 예에 따른 따른 무선랜 시스템에서 다중 사용자 전송을 위한 방법은, 제1 방향성 안테나 및 제2 방향성 안테나를 포함하는 STA이, 제1 방향성 안테나 및 제2 방향성 안테나를 위한 방향성 CCA 동작에 따라 제1 방향성 안테나를 위한 제1 카운트다운 절차 및 제2 방향성 안테나를 위한 제2 카운트다운 절차를 개별적으로 수행하는 단계, 제1 카운트다운 절차가 제2 카운트다운 절차보다 먼저 완료될 때 제1 방향성 안테나를 프라이머리 안테나로 결정하는 단계, 제1 카운트다운 절차의 완료시점을 기준으로 임계시간 전부터 완료시점까지 제2 방향성 안테나가 아이들(idle)인지 여부를 판단하는 단계 및 판단에 따라 제1 방향성 안테나 및 제2 방향성 안테나를 기반으로 복수의 스트림을 전송하는 단계를 포함한다.
